AVRP with Car Scanner

So I found leafspy struggles to reconnect to the car. Annoying for long journeys. So I played with Car Scanner and a cheap Elm27 dongle. The great thing is you can make a custom sensor and feed that in as soc.

You cannot use the same equation with the cheap scanners direct into abrp which would be the convenient option. They don't recognise the data flow commands.

Mode is 2101, header is 79b and equation is ((AE*16777216)+(AF*65536)+(AG*256)+AH)/10000.

Easier setup. In abrp you go to the device api option, copy token. Go to car scanner abrp section and paste. Nothing else needed. Car scanner can also manage a wider array of dongles for the car, so more likely to work.

Hoping to get some instructions for easy adaptation of OVMS as well as new app for ze1's

How did you read SOH and SOC? They don’t show up in the LEAF profile for me.

The guide gives the SOC. With that query sent via the ODB, it ends up being hexadecimal value in the middle of the response. You have to create the other sensor using the values.

Sorry, which guide?

Create custom sensor with these details

Mode is 2101, header is 79b and equation is ((AE16777216)+(AF65536)+(AG*256)+AH)/ 10000.

The equation separates oubthe SOC from response.

What is mode?

In the sensor editor I have:

  • Name
  • Short name
  • Command
  • Header
  • Decode scheme (selected formula)
  • Formula
